Nope. Other than a few FTF's in a couple of my revolvers and ONE "stovepipe" in a semi-auto (which I no longer have)....I've never even had any stoppages (in my current guns). All my current guns function flawlessly......so far.

Oh, there was the small broken part that caused a semi-auto (I used to have) to become a full-auto. But that didn't render it inoperable, so I guess it doesn't count here.
